Participants in both groups will receive the same surgical dressing on the abdomen after the procedure. Both groups will thus be bandaged as if after a conventional 4 port laparoscopic cholecystectomy with a total of 4 dressing strips. In the TV NOTES group these dressings will be stained red to simulate light seepage from the "wound". These dressings are obligatory for the first 72 postoperative hours.
